Why Drain Your Home Plumbing System?

Before we dive into the steps of draining your home plumbing system, it’s essential to understand why this task is necessary. Over time, sediment and debris can build up in your pipes, causing blockages that can lead to clogs or even burst pipes. Draining your plumbing system helps to clear out this buildup and maintain the health of your pipes. Additionally, draining can also help prevent frozen pipes during colder months by removing excess water from your system.

Materials You Will Need

To successfully drain your home plumbing system, you will need a few basic materials. These include:

  • Prepare a bucket or a sizable container to collect the water.
  • Towels or rags to clean up any spills
  • A pair of pliers
  • A pipe wrench
  • An adjustable wrench
  • A hose (optional)

It’s best to have these materials on hand before you begin, so you don’t have to interrupt the process. Additionally, it’s a good idea to wear protective gloves and eye gear when working with plumbing systems.

Step 1: Locate the Main Water Valve

Before draining your home plumbing system, you must locate the main water valve. This valve controls the flow of water into your home and is typically located near the water meter or in a utility closet. Once you’ve found it, turn the valve clockwise to shut off the water supply.

Step 2: Open All Faucets and Drains

After turning off the main water valve, go through your home and open all faucets and drains. This step will help release any remaining water pressure in the system.

Step 3: Locate Drain Valves

Next, you’ll need to locate the drain valves for each of your plumbing fixtures. These are typically found underneath sinks and behind toilets. If you have a basement, you may also have drain valves located there.

Step 4: Drain the Water

Using your pliers or wrench, slowly open the drain valves and let the water flow into your bucket or container. You may need to use a hose to redirect the water if it’s not draining directly into the container. It’s essential to do this step carefully and slowly to avoid any spills or accidents.

Step 5: Flush and Clean

Once the water has been drained, you can flush your toilets to remove any remaining water from the tanks. You can also use a mixture of hot water and vinegar to clean out your drains and pipes, helping to remove any buildup or debris.

Step 6: Refill Your System

After cleaning and flushing, it’s time to refill your plumbing system. Start by closing all the drain valves and faucets and then turn on the main water valve. Slowly turn on each faucet and let the water run for a few minutes to flush out any air pockets in the pipes.


Congratulations! You have successfully drained your home plumbing system. Remember to do this maintenance task at least once a year to keep your pipes in good condition. Additionally, if you encounter any issues during this process or notice any unusual signs in your plumbing system, it’s best to consult a professional plumber for assistance.
